Current proposal is something like this:
public interface TailableCursor<T> extends MongoCursor<T> { /** Move to the next document if available, otherwise return null. */ T tryNext(); }
Normal usage would just use the existing MongoCursor interface (which extends Iterator and adds a close() method), but for users that don't want to block waiting for the next document, the non-blocking tryNext() method can be used, e.g.
while (true) { Document doc = cursor.tryNext(); // do other useful work here }
